ADHESIVE-STRIP-FEEDING MACHINE;

Application filed February 25, 1924. Serial No. 695,076.

To all whom it may concern:

Be it known that I, BENJAMIN VAUGHAN, a citizen of the United States,and a resident of Kansas City, county of Jackson, State of Missouri,have invented a certain new and useful Improvement inAdhesive-Strip-Feeding Machines, of which the following is a completespecification- This invention relates to adhesive strip holding,moistening and cutting devices, and is designed for use primarily inshops and stores and the like where articles sold are wrapped in paperfor securement around the articles by means of the adhesive strip. Thegeneral object o-f'the invention is to produce a simple, strong,inexpensive, durable and efiicient device of this character, in whichmeans are provided for preventing accidental back feed of the strip orstrips or such movement thereof as will produce unnecemary slack in suchstrip'or strips. A further object is to produce a device of thecharacter described, which will accomodate one or a pair of independentstrips, and which will permit of one of the strips being used withoutaflecting or interfering with the remaining strip.

With these general objects in View and others as will hereinafterappear, the invention consists in certain novel and useful features ofconstruction and combinations of parts as hereinafter described andclaimed; and in order that it may be fully understood reference is to behad to the accompanying drawing, in which Figure 1 is a perspective Viewof a device embodying the invention, as equipped, with a pair ofadhesive strips.

Figure 2 "is a vertical longitudinal section taken on line IIII ofFigure 3.

Figure 3 is a vertical transverse section taken on the line III-III ofFigure 2.

Figure 4 is a vertical transverse section taken on the line IV-IV ofFigure 2.

Referring to the drawing in detail, a frame or support is of hollowrectangular form, consistin of sides 1 and ends-2, the former at asuitable point being provided with o posite notches 3 for receivin theflat en s 4 of a transverse shaft 5, an said shaft in conjunction witha. circular partition and a pair of side disks, forms reels ashereinafter explained. As shown there are two reels, one consisting of awood or equivalent core 6 journaled on shaft 5 and forming the mount fora roll 7 of adhesive paper.

11 at the opposite sides respectively of the rolls of paper andjournaled on the shaft, form the reels hereinbefore mentioned. Toprevent accidental turning movement of one roll when the other is beingunwound, a friction brake 12 bears against the partition 9, and issecured as at 12 tothe adjacent end wall of the frame or support. Withthis brake applied, either roll of adhesive strip or tape can be unwoundwithout in any way disturbing or affecting the companion roll.

A pair of spring plates 13 are pivoted as at 14 to and within the frameor so port and bear upon and at the opposite si es of the double reeldescribed, or the single reel if one only is employed, as may be .thecase where adhesive tape of greater width than that shown, is desired,it being noted that said spring plates are provided near their upperends with notches 15 engaging the shaft 5 near its ends so as to retainthe same against dislocation from notches 3, and that the upper ends ofthe said spring plates are provided with outwardly projecting ears orhandles 16 for convenience of manipulation To centralize the reel orreels as the case may be on shaft 5, with respect. to other elements ofthe device hereinafter mentioned, set

screws 17 are mounted in the side walls and bear against the outer sidesof the spring plates. By means of these set screws the reel or reels canreadily be centralized as explained, and the spring; plates can becaused to exert sufficient pressure on the reels to prevent too greatfreedom of rotation of either and insure the instant checking ofsuchrotation when effected by "means of a pull on the respective ta orstrip.

Located in the space near e front end of the frame,,is a liquidreceptacle or water pan 18, the same being supported on a tray 19provided with depending side flanges 20 secured by screws 21 or the liketo the sides of the frame, the liquid receptacle or water pan 18, comingpreferably flush with the upper edge of the frame. The said receptacleis preferably provided with a central transverse rib 22, as a rest for abrush or moistening device 23 for conducting water by capillaryattraction -.to and above the top of the receptacle at the front endthereof, and through an opening provided between such end and the frontend or margin of a cover24 pivoted as at 25 to and within the frameadjacent the reel or reels. The cover 24 is provided at its side marginswith upwardly projecting grooved ribs 26 for slidingly receiving acutter bar or plate 27 adapted to hold the free end of the strip or tabdown fiatlyon the cover strip so that as the said strip is drawnforward'beyond the said cover and cutter, its adhesive face, which isits under face, will be moistened by contact with the brush. I To insureproperoperation of the device the cover strip should be clamped firmlyin place, and thls is accomplished by providing it with a pair oflaterally projecting pins 28 for engagement with perforations in a pairof spring catches 29 secured to opposite sides of the base or frame, theupper ends of the catches tened surface of the adhesive strip wouldengage the cover and thus make 1t necessar being flared as shown mostclearly by Figure 4, so that the cover plate will always passbetween'them when swung down to operative position.

From the foregoing it will be apparent that regardless of the characteror strength of' the pull on a tape, the friction plates 13 will preventthe respective reel from rota-ting too freely and thus pay out slackbetween the reel and the cover. however, that the strip shall not beaccidentally drawn back between the cover and the cutter plate, as,should this occur, the moisto refrain from the'use of the machine untilthe cover could be cleaned and dried and the parts reassembled. It willalso be noted that the cutter late is provided with a longitudinal slot30 or access to each strip- This is to enable the operator to properlyposition the tape and feed the same forward beyond the front end of thecutter to a position to where it can be readily gripped by handpreliminary .to such further feed as shall be necessary to produce astrip of proper length for the work in hand, it being obvious that thestrip being moistened as it'is drawn forward, can be readily severed bythe front end of the cutter plate by drawing the strip backward andlaterally against such end. The cutter late is provided with alongitudinal rib 2i positioned to form a. guide between the paper stripsor tapes u' on' the cover, and the said plate, when the evice is adaptedfor use with a single reel for a wide strip or tape, is inverted so thatthe fibis out'of the way and therefore functioness. 1 Across the rearend of the cutter plate and secured to the cover, is'a transverse bar 31formed at suitable points with upwardly projecting keepers 32 whereinare pivoted It is also essentialend of the paper or tape fiat? wardly,as the catchesyare unyielding as regards such movement of the paper.

When it is necessary to replenish the liquid in the receptacle 1 8, thecover can be swung upwardly in an obvious manner, after firstpressing-the catches 29 outward slight- 1y. The cover is returned to itsoriginal position by pressing downwardly upon its front end until thepins 28 snap in to the openings in said catches.

To guard against pivotal movement of the spring plates. 13 dueto theloosening of the nuts 34 on retaining devices a or screws 14, short bars36 are secured to the inner sides ofthe frame and interposed between thespring plates 13 and the said nuts, as shown most cllearly'by Fi e 3.

From the above descrlption it will be apparent that a device of thecharacter set forth is shown and described .as embodythe characterdescribed,

the combination of a support, a reel thereon for a roll of adhesivepaper or tape, a tank for holding a liquid, a cover for but terminatingshort of the front end of the tank, a
